Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

HONOLULU — New imaging data may explain how transcutaneous afferent patterned stimulation (TAPS), a noninvasive, wearable therapy, works in patients with essential tremor (ET). In a small study that ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Abstract: With the continuous development of wireless communication technology, orthogonal frequency division multiplexing (OFDM), as an efficient modulation technology, has been widely used in ...

Unlike OFDM and OFDMA, both of which modulate information within the time-frequency domain, OTFS does so within the Delay Doppler domain Certain high mobility environments, such as high-speed trains, ...
